10 Stability and reactivity
-
Reactivity
-
Chemical stability
-
Thermal decomposition / conditions to be avoided:
No decomposition if used according to specifications.
-
Possibility of hazardous reactions
Violent reaction with water at high temperatures
Diluting or dissolving in water always causes rapid heating
Strong exothermic reaction with acids
Reacts with light alloys in the presence of moisture to form hydrogen
-
Incompatible materials:
Light metals, acids, ammonium compounds.
-
Hazardous decomposition products:
Formation of hydrogen in case of reactions with aluminium or light metal alloys.
Formation of ammonia in case of reaction with ammonium compounds.
-
Additional information:
The product reacts with carbon dioxide out of the air forming sodium
carbonate and sodium hydrogen carbonate.
The product is hygroscopic.
11 Toxicological information
-
Information on toxicological effects
-
Acute toxicity:
-
LD/LC50 values that are relevant for classification:
Oral LD50 2000 mg/kg (rat)
-
Primary irritant effect:
-
on the skin:
Strong caustic effect on skin and mucous membranes.
-
on the eye:
Strong caustic effect.
Danger of loss of sight is possible.
-
Sensitization:
No sensitizing effect known.
-
Additional toxicological information:
Swallowing will lead to a strong caustic effect on mouth and throat and to the danger of perforation of esophagus
and stomach.
12 Ecological information
-
Toxicity
-
Aquatic toxicity:
No further relevant information available.
-
Type of test Effective concentration Method Assessment
Leuciscus idus 133 mg/l LC50 (48 h)
-
Persistence and degradability
No further relevant information available.
-
Ecotoxical effects:
-
Remark:
Hamful effect on fish, plankton and other waterorganism by pH shift possible.
-
Behaviour in sewage processing plants:
None bacterial inhibition after neutralisation..
-
Remark:
On proper use no troubles in clarification plants.
-
Additional ecological information:
Does not cause any biological oxygen consumption. After neutralization, the toxicity is reduced. Toxic effects refer to
pH-values below pH<6 or above pH>9.
-
General notes:
Do not allow to enter drainage system, surface or ground water.
Water hazard class 1 (Assessment by list): slightly hazardous for water.
